Echinochloa crus-galli (L.) P. Beauv., Ess. Agrost. 1: 53, 161, 169, pl. 11, f. 2. 1812.

Basionym.

Panicum crus-galli L., Sp. Pl. 1: 56. 1753.

Type.

Herb. Burser 1: 303, sine dato (UPS).

Notes.

There has always been a great deal of confusion about the type; see, e.g., Hitchcock (1908) or Gould et al. (1972). In fact, all original material came from North America and belongs to E. muricata ; in 1753 E. crus-galli , from Eurasia, was not yet a widespread introduced species in North America. Crespo et al. (2020b) formally proposed to conserve the binomial P. crus-galli with a conserved type based on the specimen Herb. Burser I: 103 (UPS), the one previously chosen as “lectotype” by Michael (1983).
